Question

Choose the correct statements among the following

I) Fatty acids are broken down to acetyl CoA before entry into respiratory pathway.
II) The F₁ component of ATPase is integral membrane protein complex.
III) Hans Krebs elucidated the tricarboxylic acid cycle.
IV) All living organisms retain the enzymatic machinery to partially oxidise glucose.

• A. I, III, IV
• B. I, II, III
• C. II, III, IV
• D. I, IV, II

Hint:

Know which ATPase subunit is integral (Fsubscript{0}) and which is peripheral (Fsubscript{1}) to avoid confusion.

Answer 1

The Correct Option is A

I) Correct — β-oxidation of fatty acids leads to acetyl CoA.
II) Incorrect — F₁ ATPase is peripheral, not integral.
III) Correct — Krebs cycle (TCA cycle) was discovered by Hans Krebs.
IV) Correct — All organisms use glycolysis as a common path for glucose oxidation.
